oh great ones,

I have an hash of array. I would like to be able to sort the hash based on the value of the array. But I cannot get to the array in the hash to be able to sort it. the example below does not work becaue I do not know how to pass the array into the sort routine.

code example : 

my %colorhash = (
CCgray   => ["0","0","0"],
CCwhite  => ["1","0","0"],
CCgrey   => ["0","2","0"],
CCBlue   => ["0","0","3"],

);

foreach $colorname (keys %colorhash) {
 for my $i (0.. $#{ $colorhash{$colorname} } ){
 print "[$i] = $colorhash{$colorname}[$i] ";
 }
 print "\n";
}

my @light2dark = numsort (keys %colorhash);

sub numsort {
 $colorhash{$a}[0] <=> $colorhash{$b}[0] or
 $colorhash{$a}[1] <=> $colorhash{$b}[1] or
 $colorhash{$a}[2] <=> $colorhash{$b}[2]
}
